PRC: Principal Response Curves (PRC) For Displaying Multivariate Main Effects And Interactions

PRC is a small \code{vegan}-based package to create and display Principal Response Curves (PRC), which are a special case of Redundancy Analysis (rda) for multivariate responses in designed experiments and repeated measurement designs. PRC expresses ordination scores as deviation from a reference, usually to visualize multivariate A-dependent effects (e.g time-dependent effects) of a treatment B in (un)balanced factorial experiments. The main user functions are \code{\link{doPRC}}, \code{\link{plotPRC}} and \code{\link{plotPRC2d}}. The easiest example is the code demo \code{PRC_pyrifos}.
